SharePlay Connectivity Issue: Asymmetric Connection Failures Between Vision Pro Generations Environment: Device 1: 2nd generation Vision Pro Device 2: 1st generation Vision Pro OS Version: visionOS 6 build 23O471 Custom App Version: Both devices running identical version Both devices fully updated to the same OS and app versions Issue Description: SharePlay connections exhibit asymmetric behavior based on invitation direction, despite successful FaceTime connectivity between devices: 2nd gen → 1st gen: SharePlay invitation fails consistently 1st gen → 2nd gen: SharePlay invitation succeeds consistently. FaceTime calls: Successful in both directions Impact: Users cannot reliably initiate SharePlay sessions from newer generation devices to older generation devices. The issue is isolated to SharePlay functionality, as standard FaceTime connectivity works bidirectionally and both devices run identical versions of the custom app.
